timing gear drive peoblem?

Hello fellas!
I just installed a e-303 cam, new lifters, and a timing gear drive set in my 91 5.0, well the car runs great but gear drive sounds like it's rubbing on the timing cover or something.... I'm confused here, it's the first set I have installed in a 5.0 so I don't know if this sound is normal or not... I know the gears wine, but there is also a rubbing noise that's coming from the front to??? Has anyone had this problem or know someone that has?

Do you have the center section ( dog-bone gears) spaced correctly? On mine I had to add some spot welds inside the cover where the dog bone would touch and then grind down the welds till I got the correct spacing.

either stampede or trojan horse was telling me that they had a gear drive, also said he had to alter the timing gear cover just a TAD, might be what your hearing

The instructions told me to grind out the rib inside the timing cover, it's the rib that keeps the chain from slaping together. The instructions say to grind the long pin that the idler gear rides on to get a clearance of .005 - .075 from the pin to the block, not the cover.. I didn't think the gears where supposed to hit the timing cover when engine is running??? I was told the crank and cam gear pulled the dog bone into the block side not cover side??? I'm not getting any metal shavings or anything in the oil so I guess I'll run it for a few more miles before I tear it back down... I hate to tear back into something that looks that good... Thanks for all your help fellas...

I took it back apart to see what was making the ugly sound.. Look what I found, the idler gear axle (small one) was chewing into the block??? The boss around the front main bearing.... My finger is pointing to it.. Let me know what you think

That's a gnarly looking finger.

Were there any shims or spacers included with the kit?
It is evidently pulling the idlers into the block like they said it would.

What brand are they?
Have a picture of the assembled drive?

Yeah that finger looks like one of my own. All twisted and beat up from years of working with our hands.
Anyways, I'm glad you got it sorted out.
I wondered about casting problems. I have seen things like this happen whenever you get a block with much core shift and now due to differences from mold to mold.

Happy gear banging and tire smoke.
